[ITK] [ITK-users] Conversion of itk::Image to other formats

[Matt McCormick]

Hi Lambert,

This example shows how to read in an unknown image type. It
demonstrates how to go between run-time type specification and the
compile-image type specification of ITK.

This approach could be used for your problem.

HTH,
Matt
